About 77Fox
77Fox is a Windows desktop app, web app and Chrome extension made by Silent Core Ltd in London. It succeeds 77FX, which used to be distributed from silentcore.uk.
What 77Fox is
A local-first workspace for AI creators and independent developers: prompts with versions and reference media, to-dos and a timeline, finances and subscriptions, world clocks and exchange rates, server and hardware monitoring, an AI assistant, and a browser extension for downloads, sponsor skipping, verification codes, page translation and page audio. Core desktop features are free; cloud AI plans are optional.
How your data is handled
Prompts, references, tasks and finance data stay on your machine. Sync is end-to-end encrypted (AES-256-GCM) through your own Google Drive; 77Fox servers hold only account, device, entitlement and short-lived verification data. Details are in the privacy policy.
From 77FX to 77Fox
77Fox is the successor of 77FX. The old product pages at silentcore.uk/77fx now redirect here, and existing installations update through the normal update channel.
